|Big's Backyard Ultra|
|Location(s)||Bell Buckle, Tennessee, U.S.|
Big's Backyard Ultra is the original backyard ultra, invented by Gary "Lazarus Lake" Cantrell of Bell Buckle, Tennessee. Participants attempt to complete a 100/24-mile loop each hour indefinitely (around woods during the day, along a road after dark). There is no predefined finish, and the winner is determined by the last loop completed by a single competitor. Otherwise, there is no winner.

In 2020, the COVID-19 pandemic precluded competitors' travelling to Tennessee, so the race was replaced by satellite events in various countries; the world title winner was Karel Sabbe in Belgium, with 76 laps, and the United States winner was Courtney Dauwalter with 68.
